2. Description of the Related Art In recent years, environmental problems such as global warming and acid rain have been widely taken up. Among them, it is said that, especially in daily life in the city, positive ions in the air due to exhaust gas increase and negative ions decrease, which adversely affects our body and environment.
It is said that when the number of positive ions is greater than that of negative ions, oxidative decay, abnormalities in the body, and aging progress, and now our bodies, environment, plant systems, and water systems are weakly acidified. Therefore, the negative ion effect is to create a missing negative ion and reduce it to neutrality. Negative ions are often found naturally in water-rich forests, waterholes, coastlines, etc., and exert a healing effect that calms the hearts of people and a metabolic activation effect of the body.

Tourmaline ores have been found so far as those that release such negative ions. This tourmaline, which is also called tourmaline, is a substance that has permanent spontaneous electric polarization, but it produces negative ions due to external stress. For example, Japanese Examined Patent Publication No. 6-104926 proposes an electret fiber in which finely divided tourmaline is fixed to or contained in an organic fiber.

Originally, however, the negative ions generated by tourmaline itself are weak, and there is no material for generating strong negative ions at any time when necessary, and the negative ions are generated independently. He was paying close attention.

Furthermore, in the market in recent years, many fiber products that pay attention to the generation of such negative ions are distributed, but how efficiently the negative ion effect can be incorporated into the body as a fiber structure. None of them even considered that point.

[0006]

In view of such background of the prior art, the present invention is used around the body to efficiently release the negatively charged particles generated from the negatively charged particle generating layer into the external atmosphere. , Its effect can be made to work efficiently, and not only the negatively charged particles reduce fatigue and stress, but also hygroscopic, water-absorbing, deodorant, antibacterial, antibacterial, moisture-permeable and waterproof. Fiber structure characterized by excellent desired additional properties such as water resistance, water repellency, and antifouling property, more specifically, fibers used in the fields of bedding, clothing, interior goods, automobile interior goods, etc. It is intended to provide a structure.

[0007]

The present invention employs the following means in order to solve the above problems.

That is, the fibrous structure of the present invention is a fibrous structure composed of two or more layers, and the fibrous structure from the fibrous structure under a condition that the repeated stress accompanied by at least one of friction or vibration is 500 Pa or more. The number of negatively charged particles in the air within a distance of 10 cm is 300 particles / cc or more, or a side material and a filler for generating the negatively charged particles are used. It is what

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The negatively charged particles of the present invention are negative ions in a broad sense. Negative ions in a narrow sense refer to negatively charged particles in the air, but in the present invention, static electricity caused by friction and vibration charges highly volatile particles, and as a result, is discharged into the air. In such cases, these are included as negative ions in a broad sense.

The amount of generated ions in the present invention is measured by injecting air containing ions between three plates (parallel plate type) arranged in parallel in the measuring device. The distance between the outer plate and the central plate is 4 mm, and the polarization electrolysis is 1000 V / m. As a measuring principle, the outer two plates have a polarization potential (+ or −), the central plate is a linear detection plate, the central plate is charged to an arbitrary potential, and air is introduced. After that, it is represented by the number of ions per unit volume generated by the potential difference after an arbitrary time has elapsed. This principle belongs to the Abelt ion counter, and the shape may be a coaxial same-cylindrical shape other than the parallel plate shape. In addition to this, the Gerdien type applying this principle may be used as the measuring device.

The amount of negative ions generated in the present invention is measured by the following method. <Measurement of Negative Ions> Device: AIR ION COUNTER IC-100
0 (manufactured by Alpha LAB (USA)) Measurement conditions: room temperature 20 ° C. ± 1, humidity 50 ± 3%, indoor area 3 × 5 × 5 m, measurement time 5 minutes, suction amount 12
L / min, sample size 20 × 30 cm Evaluation content: measurement time 5 minutes The average amount of negative and positive ions generated is measured.

The measurement procedure is as follows: (1) Eight 20 × 30 cm evaluation target fabrics are folded and
Make 5 cm x 15 cm. Do not fold futons or other items that are difficult to fold. (2) Hold both ends of the sample obtained in (1) with both hands.
Move within a distance of 10 cm from the measurement part of the ION COUNTER. (3) Use both hands to rub the sample up and down, centering around the center.
For thick materials such as futon, tap the center of the sample with both hands. (4) The above measurement procedures (1) to (3) are repeated three times, and the average value is used as the generated ion amount (unit: pieces / CC). (5) Under the conditions of (3), the friction is 500 Pa or more in dynamic friction, and the repetitive stress is 500 Pa or more.

The fact that negative ions have the effect of healing humans is clear from the fact that humans are healed in forests, waterholes, coastlines, etc., which are naturally rich in water. Therefore, the present invention has diligently studied whether such a healing effect can be achieved more efficiently by a specific fiber structure.

[0016] In a product which normally generates negative ions, the negative ions are very rarely generated in a stationary state. Further, most of the negative ions generated in the middle layer of the fibrous structure composed of two or more layers such as the cotton pad of the futon are blocked by the side ground and the like, and the effect cannot be sufficiently obtained. Therefore, as a result of diligent studies on how to increase the generation of negative ions and how to efficiently take them into the body, the present inventor has found that repeated stress with at least one of friction or vibration In the presence of the presence, by generating a negative ion that is efficiently released into the external atmosphere, and by constructing a fiber structure composed of two or more layers that can effectively exert its effect, It is the best way to efficiently generate negative ions into the body at the same time as generation.

In this case, it is desirable to have stronger friction and vibration, but the condition of friction that can occur in actual life depends on the surface roughness of the product, but in dynamic friction, a repeated stress of 500 Pa or more is applied. Is mandatory. The content of the friction is not particularly limited, but for example, friction between the skin and the fibrous structure is preferable, and a fibrous structure and a fibrous structure such as underwear and a futon are also preferable.
In addition, it is preferable to rub the threads of the warp and weft threads within one fiber structure, and to rub the single threads within one thread. Especially, to make the static friction coefficient large, the threads consist of single threads with irregular cross-section. In the fiber structure,
The friction between the fibrous structures gives favorable results for the generation of negative ions.

Further, the vibration may be in either a high frequency region or a low frequency region, but a large amplitude and a large frequency give a good result to the generation of negative ions. Therefore, the amplitude is preferably 0.1 mm or more. And 2Hz
As described above, it is preferable that the amplitude is 1 mm or more and the frequency is 3 Hz or more, and particularly preferably the amplitude is 2 mm or more and the frequency is 5 Hz or more.

That is, by using them in an environment where vibration and friction are likely to occur, such as around the body, friction and vibration are always generated and negative ions are always generated.

It is important that the fibrous structure of the present invention is such that the number of negatively charged particles in the air within a distance of 10 cm from the fibrous structure is 300 particles / cc or more. The number of such negatively charged particles is preferably 1000 particles / cc or more. It is generally said that when the number is 1000 / cc or more, the effect is the same as when the water tank is on the side of the waterhole. If it is less than 300 / cc, a sufficient effect due to negative ions cannot be obtained.

In addition, the layer referred to in the present invention includes not only a layer formed of fibers serving as a skeleton forming a fiber structure but also a layer formed by laminating and a coating layer formed by using a coating agent. For example, one coated fabric or a film-laminated fabric has two or more layers in structure.

The form of the fibrous structure comprising two or more layers of the present invention is, for example, a futon, pillow, blouson, or other surface layer such as side material, surface material, lining material, and inner filling layer such as stuffed cotton. Is preferable, and a laminated structure is also preferable. The laminated structure referred to here is a structure formed by stacking two or more layers, and may be a fibrous structure in which all of the layers are combined by laminating, coating, or the like, or, like the outer material and the lining material, A fibrous structure in which a part of each layer is bonded may be used, or a fibrous structure that does not have a bonding portion and can be easily detached, such as layering, may be used.

In the fibrous structure of the present invention, in order to efficiently generate negative ions, at least one layer constituting the fibrous structure is preferably a negatively charged particle generation layer containing a negatively charged particle generator. . Further, in order to increase the generation of negative ions, it is more preferable that at least two layers contain a negatively charged particle generator. The negatively charged particle generator is not particularly limited as long as it generates negative ions due to the above-mentioned vibration and friction. Further, the negatively charged particle generating layer is preferably composed of fibers, and is preferably composed of a resin other than fibers such as a laminate layer or a coating layer.

The negatively charged particle control layer of the present invention is a layer in which negative ions in the air are difficult to permeate, and the negatively charged particle permeable layer is a layer in which negative ions in the air are easily permeated.

The fiber structure of the present invention diffuses the generated negative ions in a desired direction and efficiently uses the generated negative ions for relaxation and the like.
At least one layer preferably contains at least one selected from a negatively charged particle control layer and a negatively charged particle permeable layer.

By providing such a negatively charged particle control layer on the fiber structure, it is possible to control leakage of generated negative ions in an undesired direction.

For example, when the fibrous structure is used in a futon composed of a side material and a filler, negative ions are prevented from leaking out in a direction other than the human body side, and the negative ions are efficiently released to the human body side to generate. To make it possible to use the negative ions efficiently, if it is a comforter,
In the case of a mattress, if the side ground below, which is not in the direction of the human body, is a negatively charged particle control layer, the space between the futon and the mattress is filled with negative ions, and the relaxation effect can be further enhanced.

Further, by providing the negatively charged particle permeable layer on the fiber structure, the generated negative ions can be released in a desired direction of the external atmosphere. For example, when the fibrous structure is used as a surface material, a blouson composed of a surface layer made of a lining material and an inner filling material, negative ions are efficiently released to the human body side, and the generated negative ions can be efficiently used for relaxation. It is preferable to provide a negatively charged particle permeable layer on the lining.

Further, in order to control the divergence direction of the negatively charged particles and enhance the relaxation effect, two layers of the negatively charged particle control layer and the negatively charged particle permeable layer are used to prevent the negatively charged particles from diverging. It is preferable to provide the negatively charged particle control layer and the negatively charged particle permeable layer in the direction in which the dispersion of the negatively charged particles is desired, and it is more preferable to provide the negatively charged particle generation layer between the two layers. With this configuration, negative ions generated in the negatively charged particle generating layer can be efficiently released to the negatively charged particle transmitting layer side. For example, when using a fiber structure in this form for a blouson consisting of a surface layer consisting of a surface material, a lining material and an internal filling material, negative ions are more efficiently released to the human body side and the generated negative ions are efficiently used for relaxation. It will be possible.

The fiber structure of the present invention can preferably take either a form wrapped with one surface layer or a form covered with two front and back surface layers. A form wrapped in one surface layer, such as a pillow or a futon,
It refers to the form consisting of one side layer and the inner packing layer.
The form covered with the surface layer of the layer means a form in which the surface layer is composed of two kinds of surface material and lining material, such as a suit.

The negatively charged molecule control layer of the present invention is preferably made of a material in which the triboelectrified column is located on the negative side of the triboelectrified column of the negatively charged molecule generating layer. By using the material located on the negative side, the negative ions generated in the negatively charged molecule generation layer can be controlled in the divergence direction of the negative ions without permeating to the outside of the negatively charged molecule control layer, and the feeling of fatigue and It is possible to efficiently obtain good effects on the body due to the generation of negative ions such as reducing stress.

Furthermore, the negatively charged molecule control layer of the present invention preferably has a light transmission area ratio per unit area of less than 83%. When the light transmission area ratio is 83% or more, the negatively charged molecules that have been generated are transmitted, and it becomes difficult to control the divergence direction of negative ions. The light transmission area ratio is more preferably less than 50%.

The light transmission area ratio referred to here means an area ratio of a portion through which light is transmitted per unit area when the cloth is imaged with parallel light. Specifically, it is as follows. The fabric of <light transmission area ratio> 5 cm × 5 cm to contrast with parallel light, a digital planning meter (Co. Uchida Yoko Ltd., KP-90) using a seek area of a portion where light is transmitted (Scm ²⁾ . The light transmission area ratio is calculated by the following formula.

Light transmission area ratio (%) = S / 25 × 100 The negatively charged molecule-permeable layer of the present invention is made of a material whose triboelectrification column is located on the positive side of the triboelectrification column of the negatively charged molecule generation layer. Is preferred. By using the material located on the positive side, negative ions generated in the negatively charged molecule generation layer can efficiently permeate to the outside of the negatively charged molecule transmission layer, and the divergence direction of the negative ions can be controlled, resulting in a feeling of fatigue. It is possible to efficiently obtain good effects on the body due to the generation of negative ions such as reducing stress.

Further, in the negatively charged molecule-permeable layer of the present invention, the light transmission area ratio per unit area is preferably 83% or more, more preferably 90% or more. When the light transmission area ratio is less than 83%, as described above, the transmission of negative ions is prevented, and it becomes difficult to effectively diffuse negative ions in the desired direction outside the fiber structure.

In addition, it has already been confirmed that carbon dioxide is not limited to bamboo and paulownia, and negative ions can be generated by carbonizing it.
It is a natural functional substance with excellent antibacterial and deodorant properties,
